thank you for your kind gesture,
in meanwhile please upload the 3.5 LCD restouch lcd code with luckfox pico max as in tutorial the changes are not stated clearly,
if you have full modified version for 3.5 inch lcd interface please provide so that i can test the 3.5 lcd

thank you very much

I cannot quite grasp your requirements.
This is the executable provided in the wiki example. You can use it to test if your screen is working properly. If you need a modified version for face recognition, please give me some time as I need to do adaptation work.

Sir, i have tried multiple to interface with 3.5 LCD but no success
i am breaking the roadblocks to you
1.Initialization

LCD_SCAN_DIR lcd_scan_dir = SCAN_DIR_DFT; // Choose the rotation angle

SD_Init(); // Initialize Micro SD
LCD_Init(lcd_scan_dir, 800); // Initialize LCD
TP_Init(lcd_scan_dir); // Initialize touch IC

How to add these? is it already added?
2.I have transferred the the main file given by you in the previous section but still it is not working

Help me out for interfacing Luckfox pico with 3.5 lcd simple code will do
thanking you in anticipation

If no observable phenomenon occurs after running the main program, it is necessary to troubleshoot potential issues with the system or hardware.

1、On the system side, please confirm the usage of the image provided in the wiki. Then, connect the screen for testing. Please note that the provided image is intended for use on SPI-NAND, and some pins of the screen may occupy pins on the SD_CARD interface. 2、If the screen still does not work, you can try running the example provided by the screen manufacturer to troubleshoot hardware issues( such as running in Raspberry Pico ).

It is essential to ensure that the screen can function properly before proceeding with further development, as it serves as a prerequisite for subsequent development work.

Respected Sir,
I dont have a resource for Rasberry Pico right now,
1.I have burnt the image and followed the steps mentioned in tutorial-NO SUCCESS
2.I have replaced the main file given by you-NO SUCCESS

Sir , you have successfully interfaced 3.5 LCD with Luckfox PICO please provide that whole folder to me i will try with it because in the tutorial the GPIO pins and program coding are wrong.
Thus provide me the workout code folder it will highly greatful

Firstly, I apologize for not understanding your actual needs earlier. So, if I understand correctly now, you're confused about controlling the 3.5 LCD, not about adapting it for face recognition, right?

Unfortunately, as I mentioned before, I have been using the examples provided in the wiki to test the screen's normal operation, and I haven't made any modifications. One issue I encountered during the process is that I intended to use an SD card as the storage medium but found that the pins were occupied. Also, I faced power supply issues when attempting to enter the root file system using USB power from the computer. You may want to check if you've encountered similar situations. If you can provide more information such as printouts when running the program, I'll do my best to help you find out the cause of the problem.

In the worst-case scenario, you may need to consider whether the screen is damaged.

Thank you for understanding the problem,
Presently i cannot interface Luckfox Pico Max with 3.5 LCD.
Therefore please provide me a folder if any code worked for you
Moreover i am also flashing the code in NAND flash
Once i am sure that LCD interface is OK,i will proceed with Face recognition
So please provide me the right code just to interface with 3.5 LCD

I used this code for testing. If you want to use it, you can directly use the main executable file (the one I provided earlier). If you need to compile it, please modify the Makefile with your SDK path (absolute path).

I hope you can provide me with the printed information of your running time to help me locate the problem you have encountered

Sir i have tried with your code but the result is same i want to attach few image how i will do
My board is Luckfox Pico Max
LCD-Pico ResTouch 3.5

Hello, here is the translation:

1、Capture the image using a screenshot tool and save it. 2、Drag the image into the chat box. 3、Click the button to insert it into the text, and the text cursor will be the insertion point for the image.
